HINTS THAT ACTUALLY TEACH

Most "teaching" sudoku apps name the technique and call it teaching. Lazy Sudoku walks you through it. Step-by-step spotting shows you where to look. Step-by-step eliminations show you why the move works. Drawn on the grid, explained in plain English. Get unstuck without being told the answer.

AD-FREE, ALWAYS

No ads. No banners. No interruptions. Just Sudoku.

We do the bookkeeping. You do the thinking.
Lazy on the notes. Sharp on the logic.
